AUTOMOBILE BUFFER.

` Application iled October y20, 1922. Serial No, 595,756.

To all (whom t may conce/ra:

lie it known that I, AsTLnY W. lVHAn'roN, a citizen ot` the llnitedStates, and a rc zidentot' Churehville, in the county of Bucks and Stateot' Pennsylvania, have invented an Improvement in Automobile Butters, ofwhich the following is a specification.

My invention relates to buffers which are adapted to'be secured eitherto the front or rear end or both ends of a vehicle such as an A meansintermediate the buffer bar and the trame or other component party ot'the vohiclc structure-- Uther objects and advantages of the inventionwill be pointed out in the detailed description thereof which follows,orwill be apparent from such description.

-In order that the invention may be readily understood and its practicaladvantages fully appreciated, reference should be had to theaccompanying drawing in which I have illustrated one form of mechanicalembodiment thereof. However, it will be un derstood that the inventionis embodiment in other than that shown and that changes in the detailsthereof may be made within the scope of the claims without departingfrom -tbe said invention.

In the drawings Fig. 1 is a top plany view of the butler deviceembodying my invention and showing the same pivotally connected to theopposite sides of an end portion ot a frame or chassis, the front endportions only of which sides are. shown; an

Fig. 2 is a transverse vertical sectional view taken along the line 2-2of Fig. 1.

-Referring to the drawings, 1 designates the endportions,l say the frontend por tions,l o the opposite sides of a frame or chassis-of a vehicle,sa'y an automobile, to the forward ends o f which the angular levers 2are pivoted by means of bolts 3 which A12 as indicated susceptible offorms of construction extend therethrough at the angles between' theforwardly and rearwardly extending arms thereof. The said bolts alsooperate to connect the ends of the sidevmembers I of the frame to theforward endsI ofthe plate' springs 4, a portion of one of which is shownin Fig. 2 of the drawing. The bolts 7:3 are retained in place by meansof castel-- lated nuts which in turn are retained in place by means ofCotter pins 6. i

It will he observed that the .forwardly extending arms of the levers 2(or rearwardly extending arms in case the said levers should be attachedto the rear end of the chassis or frame) extend upwardly and areprovided with eyesor loops 10 at their' outer ends within which thetubular buffer bar 11 is secured. The eyes or loops 10 are clamped uponthe tubular bar by means of screw bolts in Fig. 2 of the drawing.

The other arms of the levers, that is the arms which extend inwardlywith respect to' the vehicle structure, also are inclined upwardly lasindicated at 15 in Fig. 2.0i' th'c drawing, and terminate in asubstantially horizontally extending flattened portion-16 through whichholes 17 extend. Bolts 20 which depend substantially vertically from theinner ends of the horizontally extending bolts 2l passthrough the holesor open'- ings 17 in the attened and widened end portions 1G oftheinwardly extending arms of the levers 2. The bolts'2l extend throughholes in the inner sides of the sidemembers 1 ot the frame or chassisand are provided upon their outer ends with nuts as indicated at 22,'The upper end portions 2 3v of'thel.

'bolts 20 are spaced fromthe inner'sides of the frames 1 by means oftubular 'spacers 25.`

The upper ends'23 'of the bolts 20 are re tained in position' upon theboltsl21 by 'means' of mits and washers 26.

The bolts 20, as already 'indicatedarepivotally vsuspended fromtheMounted upon the bolts 20below the inner horizontal widened end inwardlyextending arms of bolts 21.

r portions 1,6 of the the levers 2111's" compressi'ble elasticrubbersleeves which are retained in place byjmeans of washers 3 1 andnuts 32, thel latter having screw-thread.A

ed engagement with the lower' ends of the bolts 20. The parts which uponthe application of `pressure 30 in the present' con: .struction consistof'- rubber but-may consist l of other similar suitableelastie material`iro lin

Ashined-e will yield and uponthe release of the constructionillustrated, are cylindrical` but may be of any other desired suitableshape. 4

lf s vehicle, such as an automobile trucli or the like, should collidewith another veli# cle or other object, the bner ber il would receivethe force of the impact end transmit the sinne to the freine, but owingto the angular construction of the levers 2 and the pnesence of theelastic sleeves, 30, the seid bar and levers would yield, thereby acting:is s cushion to lessen the shock.

By the employment of rubber, or a similar material having likecharacteristics as :i snbstitute therel'on as cushioning nniterinl, lhere provided means whereby ,greater prin tection is scoured againstbreakage ot' any of the parts of n vehicle in case of collision. 'l hisis due to the feci. that in practice the limit compression of the rubberis not reached so that a cushioningr eii'ect is always present; Whereasin the case of coiled springs, when such. springs have been compressedso that the sides of their coils are in contact there 'is no furthercushioningr effect with the result that there is greater probability ciinjury to the vehicle. This probability is greatly decreased when rubbersleeves such as those indicated :it 30 :ire employed.

Hnviiw thus described ni f invention. what n l claim und desire toSecure by Letters Petent is l. In :i buffer for vehicles., the combine*tion of levers pivoted intermediate their ends to the opposite sides osuch vehicles either ut the vfront or rear end il'iercof` the inner endsof which are provided with open ings therethrough. u buffer bei' carriedupon the' outer ends of the said levers, vertically extending boltssupported by the vehicle freine and extendingthrough said openings, :indrubber sleeves secured on seid bolts underrieeth the said inner ends and|n'essin; upwardly against the saine.

2. In a buffer for vehicles, the combination of leveis pivotedintermediate their einls to the opposite sides of such vehicles eitherat, the Afront er rear thereof, 'the inner ends oli which :are providedwith openingsv there-- through, n butler luncerried upon the outerendsoi' seid levers, bolts supported by the vehicle traine undextending; through seid openings. rubber sleeves on said bolts one endof @zich of which is in contact with one side el the inner end ot' oneof sind leve-rs, end adjustable means upon the Said bolts for retaining;the said sleeves thereon and for compressing the saine against the innerends of said levers.

ln testimony that l claim the foregoing as my invention, l havehereuntovsigned my nume. this 21st day of linguist, 1922.
